Description Marcelo Bossoni 2016-03-20 15:07:11 UTC

My panel stopped showing, so I removed config file and everything went back to normal.
So I started making my customizations (placing some launchers, switching to Icon Only task, etc.)
When I tried to switch to Application Menu (cascade menus), plasma hanged.
Tried several times, same results.

Reproducible: Always

Steps to Reproduce:
1. Switch alternative menu launcher to Applications Menu (cascading menus)

Actual Results:  
Plasma hangs

Expected Results:  
Applications menu become my app launcher and plasma does not hang.

and it hangs every time?

Can you do the following:

recreate the freeze

open a terminal (using alt+space to start krunner)

type

sudo gdb --pid `pidof plasmashell`

wait for it to load then:

"thread apply all bt"

and paste the result here.

Ok,
I feel dumb now. I could not reproduce the bug anymore.
One thing I can tell though is that apparently, I was out of disk space when bug happened, so maybe something with temp files?

Anyway,
I think it can be closed.
If I face this bug again, I reopen it with the stack trace.

OK. Thanks for reporting back.
